Engine serial numbers on Z1/KZ 900's began with Z1E. (for engine) Serial numbers on Z1's began with Z1F (for frame) Frame serial numbers on KZ900's began with KZ900. From there they were either an "A" model (standard) or "B" model (LTD) The rest of the serial number would normally be six digits. If the bike was made in North America the digits began with 5 followed by five more digits. All of the B models were made in North America.
I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.
